Xulashada iyo Codsiga
Xulashada iyo codsiga amplifiers.
Waxaa jira qaybo badan iyo noocyo badan oo amplifiers hawlgalka isku dhafan, kuwaas oo ay tahay in la doorto si macquul ah oo loo isticmaalo si waafaqsan shuruudaha dhabta ah ee isticmaalka.
(1) Isku day inaad isticmaasho amplifiers hawleed isku dhafan oo ujeedo-guud ah.Marka nidaamku isticmaalo amplifiers hawleed badan, inta suurtogalka ah si loo isticmaalo cod-weyneeye badan oo isku dhafan oo isku dhafan, sida LM324, LF347, iwm. waa afar cod-weyneyaal oo isku dhafan oo isku dhafan.
(2) Doorashada dhabta ah ee cod-weyneeye hawleed isku-dhafan, laakiin sidoo kale tixgeli dabeecadda isha isha (waa isha korantada ama isha hadda), dabeecadda culeyska, korantada wax-soo-saarka cod-weyneeye isku-dhafan iyo hadda si loo daboolo shuruudaha, deegaanka xaaladaha, cod-weyneeye-hawleed isku-dhafan oo loo oggol yahay inuu shaqeeyo kala duwanaansho, kala duwanaansho korantada shaqaynaysa, isticmaalka awoodda iyo mugga iyo arrimo kale si loo buuxiyo shuruudaha.Tusaale ahaan, kor u qaadida calaamadaha AC sida maqalka iyo muuqaalka, waxa aad u habboon in la doorto cod-weyneeye hawl-gal ah oo leh qiime beddelasho weyn;Si loo habeeyo calaamadaha DC ee daciifka ah, waxa aad ugu habboon in la doorto cod-weyneeye-hawleed leh oo saxnaan sare leh (tusaale ahaan, awoodda hadda jirta, korantada wax kala saarta, iyo qulqulka heerkulka ayaa aad u yar).
(3) Kahor intaan la isticmaalin, waxaa lagama maarmaan ah in la fahmo qaybaha iyo xuduudaha korantada ee cod-weyneyaasha hawlgalka ee isku dhafan, iyo in la caddeeyo qaabka xirmada, habaynta hogaanka dibadda, fiilooyinka biinanka, kala duwanaanshaha tamarta korontada, iwm.
(4) Shabakadda gariirku waa in lagu xidhaa sida loo baahan yahay, iyada oo la tixgalinayo xadhkaha xadhkaha goosha ee ku yaala goobta uu awoodo in uu gariiro.
(5) Cod-weyneeye-hawleed isku-dhafan waa udub dhexaadka wareegga elektaroonigga ah, si loo yareeyo burburka, tallaabooyinka ilaalinta habboon waa in la qaadaa.
Tilmaamayaasha iyo Tilmaamaha
Tilmaamayaasha xulashada cod-weyneeye hawleed iyo habraaca naqshadaynta codsiga
Ficil ahaan, amplifiers hawleed guud oo ujeedo ah waa in loo adeegsadaa intii suurtagal ah, sababtoo ah way fududahay in la helo oo kharash-ku-ool ah, kaliya marka nooca ujeeddadu aanu buuxin karin shuruudaha, waxay isticmaali karaan nooc gaar ah, kaas oo yarayn kara kharashka. laakiin sidoo kale way fududahay in la hubiyo sahayda.
Iyadoo horumarinta tignoolajiyada qaan-gaarka ah, codsiga cod-weyneyaasha hawlgalka ayaa noqda mid aad u baahsan, iyo marka la eego noocyada kala duwan ee cod-weyneyaasha hawlgalka, waxaa jira tilmaamo farsamo oo caadi ah oo loogu talagalay doorashadooda.Tani waa in la doorto in la buuxiyo shuruudaha, laakiin sidoo kale si loo badbaadiyo ilaha xogta ayaa door weyn ka ciyaartay.Tilmaamayaasha xulashada inta badan la isticmaalo waa:
Tallaabada ugu horreysa waa in la doorto danab.Maaddaama cod-weyneyaasha intooda badan loo soo saaro codsiyada warshadaha ay yihiin ± 15V, laakiin iyadoo la tixgelinayo in loo sameeyo aaladaha gacanta ee ka shaqeeya 3V (ama ka hooseeya 5V), taxanahan ± 15V waa laga saari karaa.Intaa waxaa dheer, go'aanka xirmada iyo qiimaha waa in lagu saleeyaa shuruudaha.
Saxnaanta Inta badan waxay la xiriirtaa kala duwanaanshaha korantada wax gelinta wax gelinta (Vos) iyo heerkulkeeda qaraabo ah iyo sidoo kale PSRR iyo CMRR.
Helitaanka Badeecada Bandwidth (GBW) Faa'iidada bandwidth ee nooca jawaab celinta danab op-amp ayaa go'aamisa xawaaraha faa'iidada leh ee codsiga la bixiyay.
Isticmaalka tamarta (shuruudaha LQ) Arrin muhiim ah codsiyo badan.Maadaama cod-weyneyayaashu ay awood u leeyihiin inay saameyn weyn ku yeeshaan qaybinta awoodda nidaamka oo dhan, hadda quiescent waa tixgalin naqshadeed oo muhiim ah, gaar ahaan codsiyada ku shaqeeya batteriga.
Wax gelinta eexda hadda (LB) waxaa saameyn ku yeelan kara isha ama diidmada jawaab-celinta waxayna keeni kartaa khaladaad la saaro.Codsiyada leh il-qabad sare ama curiyeyaasha jawaab celinta impedance sare (sida cod-weyneyaasha ku-meel-gaadhka ah ama isku-dhafka) waxay inta badan u baahan yihiin qulqulo eexasho hoose;Galinta FET iyo CMOS op amps guud ahaan waxay bixiyaan qulqulka eexda wax gelinta aad u hooseeya.
Cabbirku wuxuu ku xiran yahay codsiga iyo op-amp ayaa loo doortay si ay ugu habboonaato shuruudaha xirmada.
Faa'iidooyinka
Faa'iidooyinka ujeedada guud op amps
Faa'iidooyinka ugu muhiimsan waa qiimo jaban, qeexitaan dhexdhexaad ah iyo noocyo kala duwan oo ikhtiyaari alaab ah.
Codsiyada
Codsiyada ujeedada guud opamps
Sababtoo ah sifooyinkooda gaarka ah, waxaa loo adeegsadaa codsiyo kala duwan.Codsiyada ugu muhiimsan waa halka shuruudaha farsamo ay dhexdhexaad yihiin.Si loo daboolo baahiyaha shaqada, dhaqaale iyo waxqabad la taaban karo.Ujeedada guud ee isku-dhafan op-yada ayaa ku habboon in la kordhiyo calaamadaha soo noqnoqda hooseeya.
